1 Claim.

This invention relates to new and useful improvements and structuralrefinements in revolving attachments for dining tables and the like, andthe principal object of the invention is to provide a device of thecharacter hereindescribed, which may be readily and convenientlypositioned on a table top to provide a revolving extension, so to speak,in order to eliminate the necessity of passing dishes around the tablein the conventional manner. A further object of the invention is toprovide an attachment which may be easily manipulated.

Another object of the invention is to provide an attachment which issimple in construction and which may be conveniently stored when not inuse.

An additional object of the invention is to provide an attachment whichwill easily lend itself to economical manufacture.

A still further object of the invention is to provide an attachmentwhich cannot easily be damaged.

With the above more important objects in view, and suchother objects asmay become apparent as this specification proceeds, the inventionconsists essentially of the arrangement and construction of parts asillustrated in the accompanying drawings, in which Figure 1 is a sideelevation of the invention, showing the same in situ on a table,

Figure 2 is a cross sectional view of the subject illustrated in Figure1,

Figure 3 is a cross sectional view, taken in the plane of the lne 33 ofFigure 1, and

Figure 4 is a cross sectional view, taken in the plane of the line 4-4of Figure 2.

Like characters of reference are used to designate like parts in thespecification and throughout the several views.

Referring now to the accompanying drawings in detail, the inventionconsists of a disc-like base 5, adapted for positioning on a suitabletable 6 and provided for this purpose on the under side thereof with apad of felt, or the like, I, to prevent scratching the table top.

The base is provided in the center thereof with a bore 8 and acounter-bore 9 and an upstanding pivot bolt ID is rotatably positionedin the bore 8, as will be clearly apparent from the accompanyingdrawings.

2 A hearing race designated generally by the reference character ll,comprises a plurality of radially extending arms I2, the same beingarranged in substantially cross-shaped formation, with the intersectionthereof rotatably positioned on the bolt ID. A rotatable roller I3 ismounted at the outer end of each of the arms l2 on a suitable screw M,the several rollers engaging and running on the base 5 The upper end ofthe bolt I0 is provided with a mounting flange l5 and a circular tabletop I6 is secured to this flange, by means of a plurality of bolts I1.

It will be noted that the table top l6 runs freely on the rollers [3, aswill be hereinafter more fully explained.

An adjusting nut I8 is positioned on a screwthreaded portion at thelower end of the bolt ill, the nut being receivable in theaforementioned counter-bore 9, in order that the same does not projectbeyond the lower surface of the base 5.

When the invention is placed in use, the attachment is positioned on thetable 6 as already set forth, and the adjusting nut l8 should first betightened sufiiciently to provide proper friction between the base 5,the race H and the top l6, whereby the three stated components are heldtogether.

This frictional contact, however, should not be too excessive and itwill be found that the table top l6 may be freely rotated upon thebearing race H, and the advantages of the invention thus become clearlyapparent.

While in the foregoing there has been shown and described the preferredembodiment of this invention it is to be understood that minor changesin the details of construction, combination, and arrangement of partsmay be resorted to without departing from the spirit and scope of theinvention as claimed.

What I claim as my invention is:

A revolving attachment for dining tables and the like, comprising incombination, a disc-like base adapted for positioning on a table, anupstanding pivot bolt rotatably positioned in the center of said base, aplurality of radially extending arms connected to said bolt, a rotatableroller mounted on the outer end of each of said arms, said rollersrunning on said base, a flange at the upper end of said bolt, a circulartable top mount- 3 4 ed! upon said flange and running on said rollers,Number Name Date arid an adjusting nut at the lower end of said 913,110Eccleston Feb. 23, 1909 bdlt. 944,153 Smith Dec. 21, 1909 BOYD C.HARTZLER. 984,479 Griswold Feb. 14, 1911 5 1,139,564 Oberg et a1.
